Sequential JIT SEQJIT- Automotive OEM customer.

Hi ,

When I create & save my LZN sales scheduling agreement - it gives me a warning " Customer: XXXXXX is not a valid JIT Customer " . Message no. NJIT_MSG124.

When I enter in data in JIT1 transaction ( or execute a SEQJI idoc) - it is unable to find the SSA & then it ends.

1. There are no duplicate SSA / CMIR is correct and i spent a lot of time going over JITV profile for the customer. And I am at my wits end on what could be wrong,

Any help would be greatly appreciated,
