Hi experts,

I would like to know, is there any way to add new class attribute on standard class by extension method.

For example, below is the standard implementation of PurchReqDocument class, and now I want to add new attribute ExpressionHierarchyProviderAttribute for my new field of PurchReqLine table which is also referrenced from EcoResCategory.RecId.

[
WorkflowDocIsQueueEnabledAttribute(true,"@SYS152689"),
ExpressionHierarchyProviderAttribute(classStr(PurchReqExpressionProvider), tableStr(PurchReqLine), fieldStr(PurchReqLine,ProcurementCategory)),
ExpressionCurrencyFieldMapAttribute('parmApprovalAmount', 'parmCurrencyCode'),
ExpressionCurrencyFieldMapAttribute('parmApprovalAmountExclTax', 'parmCurrencyCode'),
ExpressionCurrencyFieldMapAttribute('parmSpendingLimit', 'parmCurrencyCode'),
ExpressionCurrencyFieldMapAttribute('parmSpendingLimitPreparer', 'parmCurrencyCode')
]
class PurchReqDocument extends WorkflowDocument implements SysErrorMessageHelpScopeIWorkflow
{

...

}

-Thanks

Hi Arif, Can you try adding new field attribute as specified below. I have not tested the functionality but compiler is not giving any errors.

[ ExpressionHierarchyProviderAttribute(classStr(PurchReqExpressionProvider), tableStr(PurchReqLine), fieldStr(PurchReqLine,TestField)) ] [ExtensionOf(classStr(PurchReqDocument))] public final class PurchReqDocument_C_Extension { }

Hi Mohit,

Thanks for quick reply.

Compilation is successful but system is not picking this attribute for PurchReqDocument class.

I couldn't find any document or example in standard class for this scenario. Can you try below code, it might be limitation that we can't add new attribute by extension but can't confirm it.

[
WorkflowDocIsQueueEnabledAttribute(true,"@SYS152689"),
ExpressionHierarchyProviderAttribute(classStr(PurchReqExpressionProvider), tableStr(PurchReqLine), fieldStr(PurchReqLine,ProcurementCategory)),
ExpressionCurrencyFieldMapAttribute('parmApprovalAmount', 'parmCurrencyCode'),
ExpressionCurrencyFieldMapAttribute('parmApprovalAmountExclTax', 'parmCurrencyCode'),
ExpressionCurrencyFieldMapAttribute('parmSpendingLimit', 'parmCurrencyCode'),
ExpressionCurrencyFieldMapAttribute('parmSpendingLimitPreparer', 'parmCurrencyCode'),
ExpressionHierarchyProviderAttribute(classStr(PurchReqExpressionProvider), tableStr(PurchReqLine), fieldStr(PurchReqLine,TestField))
]
[ExtensionOf(classStr(PurchReqDocument))]
public final class PurchReqDocument_C_Extension
{
}
