# Process mail dates, acknowledgements, and file creation

This workflow updates mail-date, acknowledgement, and create-file markers on a legal case, inserts letter-request records when correspondence is required, and submits the LegalNet letter batch job through Appworx.

| Field | Value |
| --- | --- |
| **Operation ID** | OP-APP-007 |
| **Trigger** | User saves [frmMailDate](../../screens/frm-mail-date.md), [frmAcknowledge](../../screens/frm-acknowledge.md), or [frmCreateFile](../../screens/frm-create-file.md) |
| **Libraries involved** | [SAIF.Application.Claim.Legal](../../libraries/saif-application-claim-legal/overview.md), [SAIF.Business.Claim.Legal](../../libraries/saif-business-claim-legal/overview.md), [SAIF.Services.Appworx](../../libraries/saif-services-appworx/overview.md), [SAIF.Services.Printing](../../libraries/saif-services-printing/overview.md) |
| **Screens** | [frmMailDate](../../screens/frm-mail-date.md), [frmAcknowledge](../../screens/frm-acknowledge.md), [frmCreateFile](../../screens/frm-create-file.md) |
| **Inputs** | Mail date, acknowledgement, and create-file field edits |
| **Outputs** | Updated legal-case fields; letter-request records; `LGN0002_LEGALNET_LETTERS` Appworx batch submission |

## Steps

1. `clsMailDateManager`, `clsAcknowledgeManager`, and `clsCreateFileManager` handle [frmMailDate](../../screens/frm-mail-date.md), [frmAcknowledge](../../screens/frm-acknowledge.md), and [frmCreateFile](../../screens/frm-create-file.md) — owned by [SAIF.Application.Claim.Legal](../../libraries/saif-application-claim-legal/overview.md).
2. [SAIF.Business.Claim.Legal](../../libraries/saif-business-claim-legal/overview.md) updates acknowledgement values, mail dates, create-file markers, and related legal-case fields (ACKNOWLEDGE workflow procedure set, `xprint_control_seq`).
3. `LegalManagerBase.insertLetterRequest` inserts letter-request records when correspondence must be generated — owned by [SAIF.Application.Claim.Legal](../../libraries/saif-application-claim-legal/overview.md).
4. [SAIF.Services.Appworx](../../libraries/saif-services-appworx/overview.md) submits `LGN0002_LEGALNET_LETTERS` batch work for LegalNet letter production.
5. [SAIF.Services.Printing](../../libraries/saif-services-printing/overview.md) supports the shared print-preview path used by the application for PDF rendering.
