Where does B/201113 refer to?

In some records in WMAP the field MAP_PAINTER does not contain the description of the map but simply "B/xxxxxx" where xxxxxx is a number. The question: where is the painter data? Below the reason for this question (in case anyone has a better idea):I need to know which steps come before the current step in a workflow. Unfortunately this is not the step with index -1, because there are parallel flows and possibly multiple previous steps, nor are there any records where this information can be fetched from (AFAIK).So I made a function (in PL/SQL) which analyses the MAP_PAINTER string in the WMAP table and it indeed extracts the required information, returning it as a table and in that way can be used in a SQL statement for a report. But with the "B/xxxxxx" field I don't have data.Tom
