Hi Hidyath,
If you already have the asset number field in FBL3N report layout and you are getting the blank values in that field, then aftero special filed configuration, you need t perform the below activity.
Call transaction SE37, enter the function module ITEM_STRUC_EXTENSION and execute it with the
following parameters:
BASIC_STRUCNAME: FAGLPOSY
EXT_STRUCNAME: FAGLPOSYEXT
EXT_FIELDS_TABNAME: T021S
I_LSTCL: D
X_TRANSPORT: ' '
If you don't have that filed, then you need to implement the BTE and given enhancement with the help of the ABAPER, then only it will works. We implemented the same and worked accordingly.
Please close the thread, once you are satisfied with the solution.
Regards,
Ravi
