Source of EVENT_CLASS_CODE column in ZX_LINES Table
SummaryRevised Purchase Order Tax Calculation
In order to calculate TAX for a revised Purchase Order, the ZX_LINES table has two records and two different values for EVENT_CLASS_CODE column, namely 'PO_CO' & 'PO_AP'. Rest all other values are same in ZX_LINES except EVENT_CLASS_CODE and EVENT_TYPE_CODE. What should be the source and join for this column, in order to pick the latest revised PO record? Thanks in advance.
