GetDocumentInfo in conjunction with MIME Service unable to find document ID on less than Full Persistence *|* -1B77F85E0B

When the GetDocumentInfo service is used in conjunction with the MIME service and persistence is less than Full the GetDocumentInfo service is unable to locate the document ID.

com.sterlingcommerce.woodstock.workflow.DocumentNotFoundException: loading document has errorNo document with ID = lsdev001:node1:124b3697989:2693771

1. When the persistence level of the BP is set to ?BP Start Stop Only? it will persist data at the first and last steps of a BP. Hence the documents and the ProcessData are not persisted. This is the reason Get Document Extraction Service is not able to get the document for DOCUMENT_ID. (which is obtained from the previous step ? MIME service).

NOTE: This documentation link will give a clear picture about different persistence levels used in GIS.

2. If the persistence of the BP cannot be increased to a higher level as it may affect the performance of the GIS DB increasing the persistence at the step-level is the best option. Minimal persistence also helps to get the required data so that Get Document Extraction Service will not throw an error when getting executed in the BP.

3. With persistence - PERSISTENCE_MINIMAL itself in the MIME service step will solve this issue. The resultant MIME document (Decoded-document) is persisted at this step and hence Get Document Information Service will be able to get this successfully without any error.
