When we try to get the CA 1 Volumes records we are able to fetch 50,000 records only on first screen of Vantage SP web Client with DC mode or RT mode, even though there are many more records to fetch.
The VKGPARMS LOGREAD parameter is used for DC mode and the CA1NMBRS parameter is used for RT mode. The default value for both these parameters is 50,000. Required to update these VKGPARMS value (maximum value is 99999999) based on the requirement.
Refer to the Vantage tech doc for VKGPARMS definitions and their values.
