delta not working for 0FI_GL_6 & 0EC_PCA_1

hello folks!!!

we are trying to get the delta uploads working for the datasources 0FI_GL_6 & 0EC_PCA_1 but its not...

at first, we did an Full upload and followed by that an Initialization and then onto the Delta Updates... the Full and the Initialization went on fine but the deltas are fetching only 0 from 0 records...

i don't understand wat the reasons are... In RSA7 of the source system, i see the LUW entries for the corresponding datasources as 0... also, in the table, ROOSOURCE of the source system, Delta method is ADDD... i've seen in a few forums that for delta to be enabled that this entry should be changed from ADDD to ABR..

we are currently in PI 2004_PI_46c patch 010.. and hence i believe that change in entry from ADDD to ABR is not required in the table ROOSOURCE..

can someone explain wat could be the reason for this and also wat needs to be done so that this situation could be overcome....

Thanks & Regards
