About NVP WorkTemps(s)

The NVP WorkTemp(s) are used to extract information from the data, and from previous steps, without the need for excess hierarchical functional map calling structure.

In other words, there are some things that you cannot easily do all on one map rule. NVP WorkTemp(s) are found at both the sepvalid map level and the zero level maps (for example, se0b002d_FIToFIPmtStsRpt). As a general rule, if the information being extracted in a NVP WorkTemp(s) is useful to most of the messages, it should be extracted at the sepavalid map level and passed into the zero level maps as parameters. In the case of adding new custom mapsteps, if you are adding multiple steps, and this information will be used in all the validation maps for those steps, extract at the sepvalid map level. For new steps, however, many of the anticipated new pieces of information needed are expected to pertain just to that new mapstep. In this case the NVP WorkTemp(s) in the new step should be used.
