I find the question interesting and so I tried to analyse the problem. Setting of max_rows attribute (described in the documentation see here and here), suggested by audrey.deruere, is a good idea, but it not worked. By trying to set max_row to any value to 50 and higher one gets error message. Event if one uses Export/Import to XML to force setting the value to a higher value one still get the same error message "The maximum rows specified in the multi-row variable set {0} attribute exceeds the system limit".
The reason on the message in the code of REST API used by "Add to Card" and "Order Now". The server side code is not readable directly, but with some tricks one can find it. It contains the following code fragment:
var mrvsErrorMessages = catUtil.validateMaxRowCountMultiRowVS('sc_cat_item', itemId, itemId, request_body.variables);
if (mrvsErrorMessages && mrvsErrorMessages.length > 0) {
var errors = mrvsErrorMessages.join();
throw new sn_ws_err.BadRequestError(errors);
}where catUtil variable is
var catUtil = new RestCatalogUtil();The code of RestCatalogUtil can be read, but can't be modified. The code of validateMaxRowCountMultiRowVS method calls GlobalServiceCatalogUtil.getMaxRowCountMultiRowVS to get the limit of the rows of
var globalCatalogUtil = new global.GlobalServiceCatalogUtil();
var varKeys = Object.keys(variablesData);
for (var i = 0; i< varKeys.length; i++) {
var varName = varKeys[i];
var varValue = variablesData[varName];
if (mrVarSetIdtoNameMap[varName] && varValue != '') {
var rowArray = JSON.parse(varValue);
var rowCount = rowArray.length;
var rowLimit = globalCatalogUtil.getMaxRowCountMultiRowVS(mrVarSetIdtoNameMap[varName],srcTable, srcId);
if (rowCount > rowLimit) {
valMessages.push('The maximum rows specified in the multi-row variable set ' + varName +' attribute exceeds the system limit.');
}
}
}(By the way, the code is dirty at least because the message will be not localized).
Finally, the code of getMaxRowCountMultiRowVS method of GlobalServiceCatalogUtil is read-only too and it forwards the call to getMaxRowCountMultiRowVS method of undocumented GlideappScriptHelper.
getMaxRowCountMultiRowVS: function(variableSetId, srcTable, srcId) {
return GlideappScriptHelper.getMaxRowCountMultiRowVS(variableSetId, srcTable, srcId);
}In other words, I don't find a way to fix the problem using Multi-Row Variable set.
As the workaround I can suggest you to use variable of the List Collector type with sys_user as the List table. It has no such limit. I personally find the User Interface of the List Collector even more comfortable, because it not displays previously added users and the User list will be displayed in more compact way:
Hi @ryanlitwiller !
I know this is an old comment. But I already create the sys property with a value of 100, when I try to change the attribute of the MRVS, to max_rows =100, it keeps showing the error..
