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.
