User Exit M06B0002 - EXIT_SAPLEBND_001

Question

Hi,
We are using a release strategy that should check the field "Quantity" in the purchase requisition (MEREQ3321-MENGE).
The Release Strategy is using a communication structure called CEBAN in which this field does not exist.
We would like to populate the field CEBAN-USNR1 with the value in the field "Quantity" in the Purchase Requisition (MEREQ3321-MENGE).
We activated user exit EXIT_SAPLEBND_001 and we try to import the value from EBAN-MENGE. The problem is that EBAN-MENGE is not filled until the document is saved.
We don't know how to import the value of the "quantity" field into the CEBAN communication structure so that the release strategy can work.
The CEBAN communication structure does not have key fields to help...
Does anyone have an idea on how to do that ?
Thank you very much.
Best regards,
Remi

In SAP standard user exit, we cannot access information which is not defined in the import parameter of user exit.
To overcome this problem, we can use following technique for accessing information outside of the User exit scope.
For Example:
In partner determination user exit EXIT_SAPLV09A_004 we cannot access document type or any sales document header information.
Go in debugging mode inside the exit. Click "Calls"..
When you check calls in user exit, then you will find SAPMV45A where VBAK or other sales document information structure are avaliable. then you can use this informaiton as follows:
Example:
CONSTANTS: C_VBAK(14) TYPE C VALUE '(SAPMV45A)VBAK',
FIELD-SYMBOLS: <FS_VBAK> TYPE VBAK.
ASSIGN (C_VBAK) TO <FS_VBAK>.
CHECK <FS_VBAK>-AUART = C_ZSQT OR
<FS_VBAK>-AUART = C_ZDQT.
SELECT SINGLE AUART
                      FROM VBAK
                      INTO V_AUART
                      WHERE VBELN = <FS_VBAK>-VGBEL.
In your case, go in debugging mode of user exit.. EXIT_SAPLEBND_001..
Click "calls"... check the programs.. and try to find out which program contains the required variable and its value..
then you can use it as explained above....
I hope it is solved...
