# `Sp_Calc_sSfu` (procedure) > 商机跟进 - **Type:** PROCEDURE - **Deterministic:** NO - **SQL data access:** CONTAINS SQL ## Parameters | # | Mode | Name | Type | |---|---|---|---| | 1 | IN | `iFlag` | `int` | | 2 | IN | `iTmpCheck` | `int` | | 3 | IN | `sFormGuid` | `varchar(100)` | | 4 | IN | `sGuid` | `varchar(100)` | | 5 | IN | `sLoginId` | `varchar(100)` | | 6 | OUT | `sReturn` | `varchar(5000)` | | 7 | IN | `sBrId` | `varchar(100)` | | 8 | IN | `sSuId` | `varchar(100)` | | 9 | OUT | `sCode` | `int` | ## Body _Body is not pre-cached. To inspect: `mysql --defaults-file=~/.my.cnf -e 'SHOW CREATE PROCEDURE `Sp_Calc_sSfu`'`._ ## Narrative **Business context:** 销售管理 → 商机跟进单据 (sales lead follow-up — `salsalesFollowUpmaster`) audit / un-audit. The 商机跟进 records visit / call / progress notes against a 销售机会 (sales chance); auditing it freezes the follow-up and flags the parent chance / chance-product as touched. **What it does:** Validates `sGuid`/`bInvalid`, then on `iFlag=1` sets `bCheck=1`, `sCheckPerson`, `tCheckDate` on `salsalesFollowUpmaster`; updates `salsaleschancemaster` and `salsaleschanceproduct` on the linked 销售机会 to record the latest follow-up state. `iFlag=0` reverses the flags and writeback. **Invocation:** Bound to `gdsmodule.sProcName` on `商机跟进单据` (sId `101251240115016035948853880`) — 销售管理.
