Picklists/Pickmaps

Often we forget one thing or other while making a Picklist. Here is some trobleshooting guideline for the same, hope you all would enjoy this
A Pickmap determines which Fields from the pick BusComp will be copied to the BusComp in which the Field with a Picklist is defined.
- When there is a static Picklist and no defined Pickmap, the user will not see a list of values to make his selection.
- When there is a dynamic Picklist and no defined Pickmap, nothing will be copied from the source BusComp.
- When the Pickmap is defined, but does not contain a mapping to a foreign key column on the base table, no reference will be saved to the base record and the update is lost.
- For Fields, that do not have a Picklist attribute defined, there should be no Pickmaps either.
- If a Pickmap is a copy Pickmap, then the value of the Field in the Picklist business component will be automatically copied into the Field of the parent business component specified by the Field property.
A Pickmap specifies instructions for copying Fields when a Picklist is used by a Field, for example to identify which Field must be populated with Picklist values when a Picklist item is chosen. Missing Pickmaps will result in Field values not being populated from the Picklist and an error could occur in the application.
