KB-1918 SAP function call reuses unspecified connectionProperties parameters


When using the SAP data connector functions a!sapInvoke(), a!sapBapiParameters() or a!sapInvokeWithCommit(), the connectionProperties parameter values once specified cannot be removed from subsequent SAP calls using the same Third Party Credential key.

The connectionProperties parameter value can be changed to overwrite previous values, but it cannot be omitted. Removing the connectionProperties parameter does not remove it from future SAP calls.


This issue has been reported to the Appian Product Team. The reference number for this issue is AN-470689.


Create a new Third Party Credentials entry with a different name and key to work around the issue. Alternatively, the application server can be restarted to reset the connectionProperties values of existing Third Party Credentials entries.
