Delta download of pricing data from R3 to CRM

Hi All,

Delta download of pricing data is not happening automatically for A*  tables .

I have created ZZDNL_COND_A* adapter objects for initial download and downloaded them from R/3 to CRM

But when ever new changes made for these  A* tables in R/3 , data is not  flowing  automatically after the initial load for the Z* adapter objects.

Every time i had to run initial load  again to sync the data between R/3 and CRM for A* tables.

I have checked in TBE31 table R3 side. and R3ac4 ,the following entry is present

00503301 BC-MID CRS_PRICES_COLLECT_DATA

Also,in table CRMRFCPAR flag DISCARDDAT is unchecked for the object.

Can anyone help me out for this issue.

Regards

Ramya
