Text variables of type Replacement Path:

This is possible to use text variables in order to handle dynamically the descriptions of formulas and selections in the query designer. This is useful, for instance, when you are using date restrictions in your query and you want to show the values listed by these restrictions in the query result. Below you will find some screenshots of a simple example:

You have created a query with 3 selections where the characteristic 0FISCPER is restricted by 3 different months as per figure below:

Next 3 figures show the details for each selection, where the characteristic 0FISCPER has been restricted by values 010.2010 for selection 1, 011.2010 for selection 2 and 012.2010 for selection3:

Picture below shows the result when you execute the query (transaction RSRT). The information provided is not clearly understandable because this is showing the description provided for the selections in the query definition (“Selection1”, “Selection2” and “Selection3”):

This is possible to make more understandable the result of this query replacing the static description of these columns by a dynamic description depending on the restriction set. In this case, using text variables you will be able to replace the description for your selection (“SelectionX” in the example) by the value that you have restricted the characteristic 0FISCPER on each of these selections. You can follow the steps below in order to use that:

In the selection definition, field “Description”, create a new text variable:

Pressing the “Create New” function:

In the next screen, you inform the “Processing By” as “Replacement Path” and the reference characteristic which you want to replace the information (that is 0FISCPER in our example). The Technical name is automatically suggested by system and it can be edited if necessary (VAR_20100503200426 in this example):

In the tab “Replacement Path” you need to inform with query object you want to replace the information (infoobject or variable) and also with data from that object should be used for replace. In our example it will be informed as Infoobject and Key respectively. You can find more information regarding the fields from that tab in the online documentation informed in item “Replacement Path Tab” of this document.

After save the new variable, it is going to be available and can be informed in the description field of our selections, as in figure below (if you enter that manually, this will require the tag “&” before and after the technical name of the variable):

This is possible to set the same variable for all 3 selections from our example:



© 2010 SAP AG 7

Now, using the text variable type replacement path, the result is that the description for each selection is going to be replaced by the value from which 0FISCPER has been restricted in that selection, as you can see in the figure below:

So, the presentation of data using this feature is more understandable. It also can be dynamically handled in case you restrict you characteristic by a variable in the selections.

Hints Regarding Issues in this area:

In case the information provided by your variable is not returning the expected value, you can try to analyze that using the debug in transaction RSRT. For instance, in query below using a text replacement path variable, this is returning # instead of the description.

In order to analyze this issue you can execute the query in transaction RSRT and entering in debug mode (“/h” + “enter”) before to press the execute button. When you reach the debug screen you can set a break point in the function module RRSV_CHAVL_TO_VALUE_CONVERT as you can see in figures below:



© 2010 SAP AG 10

After that, you can continue pressing “F8”. The code should stop in the break-point set as in the image below:

In the ABAP Stack area, by double clicking in FORM ELTTXT_VAR_REPLACE this is possible to analyze the values passed to function module RRSV_CHAVL_TO_VALUE_CONVERT:



© 2010 SAP AG 11

Some interesting information is passed to the function module by structure L_S_VAR_LRECH, as you can see below:

Backing to the code, you can set a break-point just after the call of FM RRSV_CHAVL_TO_VALUE_CONVERT and verify the value returned by that FM in the variable L_REPLTEXT:

Note that in this case L_REPLTEXT is “#” which is our problem.

Checking the values passed to that Function Module in structure L_S_VAR_LRECH, we can see that L_CHAVL in this case is K12010010 and the L_S_VAR_LRECH- FOFFSET is 0010. This explains the issue: L_S_VAR_LRECH- FOFFSET= 0010 means that an offset of 10 has been set to the value “K12010010”. In this case it will remove all the information from L_CHAVL. In such case system is programmed to show “#” instead of blank.



© 2010 SAP AG 12

This is possible to confirm that FOFFSET is responsible by the issue if you change the value for L_S_VAR_LRECH-FOFFSET in the debug mode from 0010 to 0:

The L_REPLTEXT should be correctly displayed after execute FM RRSV_CHAVL_TO_VALUE_CONVERT with L_S_VAR_LRECH-FOFFSET=0, as you can see below:



© 2010 SAP AG 13

Detailing this issue:

The information from L_S_VAR_LRECH comes from table RSZGLOBV. In this case in order to fix the issue you need to maintain the correct OFFSET for your variable in that table (for this example the variable is TEXT_VAR_1):

Replacing the FOFFSET from 10 to 0, for instance:

After that, this is required to regenerate the query in transaction RSRT:



© 2010 SAP AG 14

So, it should return the desired results executing the query after the procedure:

Note: You can execute the FM RRSV_CHAVL_TO_VALUE_CONVERT in transaction SE37. You can use the values passed to this FM in the debug mode as reference and this is also help in the analysis of issues in

this area.

Replacing texts and/or Key:

You can see in the previous example that this is returning the KEY of characteristic 0FISCPER and not the text as in some other examples from this document (“K12010010” instead “OCT 2010”). This is because the information from RSZGLOBV stored in the field FLAGR. If you want to change that you can select the option FLAGR = 3 instead of 1 for that variable:

In case it is set to 3, the text is going to be displayed in the query result:

Note: It is not recommended to change values directly in the tables. The idea in this case is just to illustrate how it works. You will reach the desired results if you manage the parameters for the variable using the Bex

Query Designer in the “Replacement Path” Tab for the variable definition.

Tables T009 and T009C – text for 0FISCPER.

In case you set your variable to be replaced by the text of 0FISCPER, the information selected by FM RRSV_CHAVL_TO_VALUE_CONVERT in this case is stored in table T009C and this depends on the Fiscal Year Variants settings from table T009.

In the example from the previous session these are the values for those tables:

T009:

T009C:
