I have researched on SDN before posting this thread, i have also tried the suggestions marked in the threads but in vain.
Please have a look at this:
1.Simple scenario i have added 2 fields to internal table (using like)
2. Call REUSE_ALV_FIELDCATALOG_MERGE with bypass buffer as X , i also ran program BALVBUFDEL to delete buffers.
But the fieldcatlog is not adding those 2 newly added fields though they are in my internal table.
I can modify the fieldcatalog regenrated out of REUSE_ALV_FIELDCATALOG_MERGE but really wanted to know why it is behaving like this?
