SAP Transport Pre-Flight Check

Open the request in SE09 or SE10, expand the object list, and copy the rows. Three columns are enough: program ID, object type and object name. Include every task in the request, not only your own.

The first cause is an incomplete request. A colleague's task in the same request is still open, or a related object sits in a different request that nobody released. The objects arrive without what they depend on, activation fails, and the log shows a problem in your object rather than in the one that is missing. SE03 answers this in a minute: it finds every request that contains a given object, and it is the single most useful check before a release.

The second is sequence. A dictionary object cannot activate before the data elements and domains it uses; a CDS view cannot activate before the tables and views it selects from; access control cannot activate before its entity; a service binding needs its definition. Inside one request the import handles most of this automatically, but across two requests it is entirely up to the order they are imported in, and getting that wrong produces a return code 8 that looks like a broken object.

The third is a part object travelling alone. A LIMU entry carries one piece of a program — the source, the texts, a screen. If the program is new in the target, the piece cannot be created and the import fails. This happens most often when a developer adds only the changed include and the whole object was never transported.

A structure change to a table that already holds data can start a table conversion during the import. On a small table nobody notices. On a table with tens of millions of rows the conversion becomes the import window, and if it is interrupted the table is left in a state that has to be repaired with the database utility before anything else can import — including the fix.

The remedy is not technical, it is procedural: check the row count in the target before release, tell Basis the conversion is coming, agree a window, and verify afterwards that no conversion is left open. Appending a field to a large table is the routine case that catches teams out, because it feels trivial in development where the table has four rows.

Workbench objects are client-independent; customising entries, variants and query definitions are not. A request that carries both has to be imported into one specific client, and it cannot be backed out in halves. If either part has a problem, both are blocked, and in a landscape with more than one client in the target system the configuration only arrives where the import ran.

Splitting workbench and customising into separate requests costs a few minutes and makes the import order explicit: structure first, content second. It also means a configuration mistake can be corrected without re-importing code, which is the situation you want to be in at nine in the evening on a release day.

A useful release checklist is short and unavoidable. Every task released. No sibling request holding a related object. The object list read once by someone other than the author. Import into quality first, with the log read to the end rather than glanced at — a return code 4 with activation warnings in quality is frequently a return code 8 in production. A smoke test of the affected process in quality. And nothing activated by hand in the target, because an object that needs manual activation is telling you the request is incomplete.

The last item is the one most often skipped and the most expensive to skip. Manually activating an object in quality makes the test pass and guarantees the production import fails the same way, with nobody there to activate it.

For a failing process rather than a failing import, the SAP issue Copilot works through root cause, checks and a safe fix, and the error diagnosis tool takes a pasted message. For code that has to survive a conversion, run it through the clean core code check. Interview preparation on change management sits in the SAP Basis question bank.
