Need some help on this badi FI_INT_CUS01 method int_post. I am using this method to modify the special gl indicator which is is not picking correctly in the standard system. Here there will be two structure one for all line items ct_items, other for accounting post line items ct_accit. Here while changing the interest indicator i do not have any fields to compare these structures. I need to modify ct_accit-umskz. I tried some code but did not get the correct trick how to read.
