Bank Posting Doc type : SA

Cus Posting Doc Type : DZ

Posting Key Dr : 40

When i'm uploading flat file in FLB2, it's giving error:

Table T049A does not have an entry with key 0512#1000123456#0001

in that 0512 is date(MM/DD), 1000123456 is Immediate Destination for Lockbox, 0001 is Number of Remi (Checks) per Lockbox.

so can u please tell me, for wat this error is and how to solve this. thanks in advance.
