another common finding of audits is, that not all (of your customer-) tables are assigned to a table authorization group — allowing everyone with S_TABU_DIS and DICBERCLS = "&NC&" to access them. Therefore, you might want to take care of this…
(Certainly, this is not always a sensible check 🙄 – it depends on the data contained in the respective tables! … but anyway many auditors check for it.)
The assignment of tables to authorization groups is defined in table TDDAT; but it only contains registered assignments. If a developer never assigned his/her table to an authorization group, it won't appear in it. So the problem is to find all tables without an entry in TDDAT plus all tables with an empty entry there. Furthermore, some "tables" are uninteresting, e.g. structures, help views and temporary or local tables, as they don't contain any sensible data.
Please, do not start Excel at this point… there is a better way!
Obviously we need a way to list all unprotected tables (no matter whether they're in TDDAT or not) and automatically exclude all table- (and view-) types containing uncritical or no data.
Therefore, we need to find DDIC objects, which…
- have no entry in TDDAT or
- are assigned to the authorization group "&NC&" (which has the same effect as no entry) or
- are assigned to an empty authorization group (same effect) and
- aren't internal tables or append structures (as they cannot contain data) and
- aren't help views, structure views or append views (which do not contain real data as well) and
- aren't tables for temporary data and
- aren't local (i.e. not transportable) ← YMMV.
Fortunately, I was bored some time ago and programmed a report for this…
- Create a new program in SE38:
- Fill in the attributes:
… and choose a suitable authorization group (P_GROUP, marked red)!
- Copy and paste the source code.
- Maintain the selection texts:
… and leave P_COUNT and P_EMPTY empty, tick "Dictionary reference" for the other ones.
- Activate and execute it.
The report shows the following selection screen on execution:
On the first tab you can:
- Select the range of Table names to inspect, e.g. "Z*".
- Choose whether or not to Check tables for data (i.e. determine whether the number of rows is > 0)
… which might heavily increase the runtime!
- Decide whether to Show empty tables (if you've selected the previous option).
The second tab is pre-filled with sensible values (YMMV):
- The Authorization group field is set to "&NC&" and empty values (only for tables that exist in TDDAT).
- The Table category is set to exclude structures and append structures.
- The View type field excludes help-, structure- and append-views as well as views without any type,
- The Delivery class option excludes tables for temporary data.
- The Package field is dynamically ❗ filled with all local packages on the system, the report runs on.
Now execute it and you'll get a result like this:
In the ALV header, you can see the number of tables matching your selection and the number without an authorization group.
- Table name — … self-explanatory.
- Short description — table description from the data dictionary.
- AuGr — assigned authorization group (usually "&NC&" or empty).
- Description — the authorization group's description from TBRGT.
- Data — whether or not the table contains any data (only available if you ticked "Check table for data").
If it contains a flash symbol, the check failed.
- Cl.-spec. — whether or not the table is client specific.
- Log — whether or not the table has "Log data changes" enabled in its technical settings.
- Del. class — the delivery class, which might give you an indication to classify the table contents.
- Package — the package the table belongs to (might point you to the "area" the table belongs to).
- Tab. cat. — the type of the table (e.g. transparent -, cluster -, pool table or view).
Furthermore, you can double-click on the following fields:
- Table name — jump to SE11.
- Short description — inspect the selected table via SE16.
- AuGr — open SE54.
- Data — show the number of entries in the table.
- Cl.-spec. — show description.
- Log — show technical table settings.
- Del. class — show all available delivery classes.
- Package — open the package explorer.
- Tab. cat. — show a list of table types.
Have fun, play around with the options and clean up your system! 😀
a check, many auditors perform on your productive SAP systems is whether any developer keys exist (in table DEVACCESS). If there are any, this might become a finding you can easily avoid (… although your system is properly protected against changes in SCC4 and SE03 :roll:).
To delete all entries from DEVACCESS on production without touching the development system (and make your developers as well as the auditors happy)…
- Launch SE14
- Enter object name "DEVACCESS"
- Select "Delete data", then click "Activate and adjust database"
- Mission accomplished
Note: This changes the activation log (go to SE11, choose DEVACCESS and click Utilities » Activation Log).
