Transaction Set Control Number
M 1AN4/9
Identifying control number that must be unique within the transaction set functional group assigned by the originator for a transaction set
The Transaction Set Control Numbers in ST02 and SE02 must be identical. The number is assigned by the originator and must be unique within a functional group (GS-GE). For example, start with the number 0001 and increment from there.

Implementation Convention Reference
O 1AN1/35
Reference assigned to identify Implementation Convention
SEMANTIC: The implementation convention reference (ST03) is used by the translation routines of the interchange partners to select the appropriate implementation convention to match the transaction set definition. When used, this implementation convention reference takes precedence over the implementation reference specified in the GS08.
INDUSTRY NAME: Version, Release, or Industry Identifier
This element must be populated with the implementation guide Version/Release/Industry Identifier Code named in Section 1.2.
This field contains the same value as GS08. Some translator products strip off the ISA and GS segments prior to application (ST/SE) processing. Providing the information from the GS08 at this level will ensure that the appropriate application mapping is utilized at translation time.
