Summary
This article will walk you through troubleshooting steps should you get the error "An internal error occurred while calling 'processDPCommandsEX' API. (Error: ERR_WIS_30270)."
Issue
My scheduled report failed to run. I received the message, "An internal error occurred while calling 'processDPCommandsEX' API. (Error: ERR_WIS_30270)."
Environment
Scheduled WebI reports, starting in 4.2 SP6 Patch 200.
Cause and Resolution
There are two known reasons for this error:
Cause #1 - Multiple Prompt Texts with inconsistent prompt properties
Prompts that use the same prompt text but the prompt properties are set-up inconsistently.
Resolution #1 - Instructions
Step 1 - For each prompt that shares prompt text, click on the Prompt Properties (Settings) icon.
Step 2 - Make sure that the optional/required check box, the default values, and all other prompt properties are consistent for all prompts that share the prompt text.
Cause #2 - Data Providers listed out of order
In WebIntelligence (WebI), data providers (queries) are processed sequentially, from left to right. When a report has more than one data provider, and one of the data providers relies upon the other for a prompt value, then the order of the data providers becomes important. The data provider sending the prompt information must be to the left of the data provider receiving the prompt information. If the order is backwards, and the report is scheduled, the scheduled report will fail.
Resolution #2 - Instructions
Step 1 - Move the data provider with the prompt value being sent to the left of any queries receiving the prompt values.
Step 2 - Run the report and save it. You should now be able to schedule your report.
