BAPI_NETWORK_COMP_ADD problem in quanity update

Hi,

I am using this BAPI - BAPI_NETWORK_COMP_ADD

to add material and quantity to network (Similar to t-code CN22).

This program is sheduled to execute at night

Everything works fine but sometime when no of materials are more (above 20) it

does not update the quantity (Material no is perfectly updated in all the cases).

However it is not always sometime it update sometime not, I checked with the data

but the data get populated perfectly infect for same set of data it did not updated at night

I execute in morning to debug and identify the problem it get updated perfectly.

Any suggestion will be helpful.

Regards

Bikas
