In workflow configuration we usually got requirements to add condition on Steps. Some time we also need to create new fields and use in the conditions.
If you want to use the new field in Workflow conditions, Simply add it in your workflow Document query from table.
For example for Purchase requisition workflow, the document query is “PurchReqDocument” .Just add your newly created field in this query.
For Amount field, the general error in conditions while activation of workflow is
A currency code must be specified for an amount field
If it is the custom field , you have to select the below highlighted properties of the field in order to select/resolve currency error on workflow configuration
Simply Click on the red Highlighted area and select currency. BOOMMM !!!! Error resolved
