I am building a map that is a conversion from a Biztalk 2002 map. The 2002 map used a 811Schema as the source schema. The 811Schema is somewhat different than the Covast ASC_X12_811_004_010_DEFAULT_X schema in that the 811Schema has HLLoop1, HLLoop2, HLLoop3, HLLoop4, HLLoop5, HLLoop6, each nested inside the other.
The Covast ASC_X12_811_004_010_DEFAULT_X schema has a HL_Hierarchical_Level_S18 instead of the HLLoops
Is there any reference material on the HL_Hierarchical_Level_S18?
