If you come across the following error in Xcelsius with either with QaaWS or BIWS (WebI):
Maximum character output size limit reached. Contact your BusinessObjects administrator. (Error: ERR_WIS_30272)
2 things you might try to solve it:
1. This error can occur when there is a mismatch between the datatype of an Xcelsius cell when sent as a prompt value to a Xcelsius QWAAS connection expecting a different datatype. eg. the xcelsius prompt sends a number but the WebI prompt expects a text.
2. change the WebI Server setting in the CMC. (Kbase article: https://service.sap.com/sap/support/notes/1370045)
[The Web Intelligence Processing Server (BO XI R2: Web Intelligence Report Server) configuration parameter Maximum Character Stream Size (MB) (BO XI R2: Maximum Character File Size) is too small for the output. Increase this value in the Central Management Console (CMC).]
