Receiver Determination Condition - not working for ISA Id

Hi Experts,

We are working on ANSI X12 and in inbound scenarios(810,852 etc) we want to split our incoming message(from customer) into PI and route it to different mapping.

Condition is based on the ISA ID we are giving in D_l06 field of the incoming message. Based on this field, we are giving 3 different maps and then routing it to the ECC system. This is failing and not reaching ECC system.

In ECC, we have maintained the customers based on there SOLD TO#.

Now, we did some analysis mentioned below -

1) When testing individual maps without giving any conditions, it is working fine and reaching ECC.

2) When giving condition for any other fields(apart from D_I06) say like DATE field etc, it is working fine and reaching ECC.

We are working in NWDS and specifically the IFlows.

Please suggest why is it not working as per our condition(D_I06).

Thanks,

Nidhi
