CASXB0064E ADVS field repeated in 3 dimensions. Collapsing into 2.

An SDF-type repeated field definition, within a repeated group definition (defined or implied), contains a BMS OCCURS clause.

This would logically yield a three-dimension array in a generated copybook. However, it cannot be internally represented by this product.

System Action:
The outer two dimensions are collapsed into one. This will render a similar two-dimension array that covers the same area of memory.
Replace the BMS OCCURS specification with multiple field macros that follow the SDF-type repeated field specification.
