Thanks for the reply, It is weird as I was able to create substitution rule for asset postings in GGB1 but could not activate it. Here is my requirement:
1. I have new depreciation area 38
2. Only specific transaction type can only post to area 38, if other transaction type used the value should be zero.
Possible solution: Always modify the value of book 38 during asset transaction (manually)
Problem: Cannot handle automatic transaction
Possible solution: create ttype to post only to book 38
Problem: I need to restrict ALL transaction type so it will not post to book 38.
I would like to know what you can suggest.
Thanks in advance!
