The implementation guide states, “This number must be unique within a specific group and interchange, but it can be repeated in other groups and interchanges.”
Does this mean that from ISA to IEA, from GS to GE, the ST02 must increment by one?
We have a trading partner that receives an 835. Within the file, there are multiple provider groups. Each provider group has a GS to GE. Within that GS to GE, can the ST02 be 0001 for each group or should the ST02 increment by 1 for each group within the file?
Can the ST02 be 0001 for each group within that file?
One 835 is going to a clearinghouse. There is one ISA-IEA. Within the file, there are multiple providers, so there are multiple GS-GE. Within each GS-GE, there is a ST-SE. Within that file, is it necessary to increment the ST02, or can that ST02 be repeated within the ISA-IEA?
The Transaction Set Control Numbers in ST02 and SE02 must be identical and must be a numeric value for implementation of this transaction set and cannot contain alpha characters.
This number (i.e., numeric value) is sequentially assigned within each functional group (GS-GE) and interchange, usually beginning with 0001 and incremented by one for each additional transaction set within the group. This number must be unique within a specific functional group and interchange but can be repeated in other functional groups in other interchanges. The Transaction Set Control Number also aids in error resolution research.
