銀行媒體檔(Map Format Data)格式，明細行流水號設置

[RainieLin]

大家好，我想請問一個關於銀行媒體檔(Map Format Data)明細行欄位設置的問題，

若明細行欄位需要設置"流水號"如下圖0001/0002/0003，是否能透過在標準功能設置，生成流水號，或是得用其他方式處理?

Hi Rainie,

You should

1. create a Numeric variable in Format Mapping Properties (Initial value can be 0, but does not have to be mentioned)
2. create a Calculation Node in the segment (as a first node in the segment)
3. in the Calculation Node increase the value of the variable by 1 (so it will be increased for each line)
4. add an element behind the calculation node
5. set the element appropriately (mapping procedure is Variable and so on)

Best regards,

Antonin

dear colleagues, you might want to consider use 'Variables' to add this exra information. In the Variables section, you create variables to store the results of simple mathematical operations.' https://help.sap.com/docs/SAP_S4HANA_CLOUD/656a410b5ce14bcd82d40b88f26d8d74/e5361718d78c40bca9a36aaa... best regards, liling
