Wrong data in PSA but correct data in RSA3

Hello Experts,

I have a issue which looks strange to me.

I enhanced the 2LIS_03_BF data source for Delivery & Item .

For one Material document there are 4 items ( 1/2/3/4) and it's respective Delivery document also have 4 items (10/20/30/40).

If i run setup for single / total Material doc the at RSA3 T code shows correct values for all items. like below

MatDoc No Material Item Delviery Doc Delivery Item

0102 1/2/3/4 546 10/20/30/40

But when i loaded the same into PSA the values are change to like below.

MatDoc No Material Item Delviery Doc Delivery Item

0102 2/2/3/4 546 20/20/30/40

No code in Info package. what the strange happend here.

Kindly suggest me with the needful.

Thanks-

Anjan
