COLLECT stmt - counter.

Experts,
Basically
DATA : Count TYPE i.
will work with COLLECT stmt as a counter.
I have DB structure having filed as RKE2_VVQ09 (QUAN type) in 4.6 C which was used as a counter filed in COLLECT stmt.
However in ECC 6.0, looks like is not working in COLLECT stmt as a counter.
So DDIC team have changed it in the DB structure from RKE2_VVQ09 (QUAN type) to char20, however it is not either working as a counter when we use COLLECT stmt (i did not test ).
So could you please let me know Whether RKE2_VVQ09 (QUAN type) will work with COLLECT stmt in ECC ?
or do I need to change this to INT4 ?
I Could not change in DB structure and test it ...that why I am asking for your help.
YOUR HELP WILL BE APPRECIATED.
Thanks in advance.

You don't have to change the DB structure. You could simply create an internal table that has fields of both types and see if either works.

Collections and counts

Greetings!
I have a procedure in the following format:
PROCEDURE test as
type p1 is table of number;
tab_t1 p1;
cursor c1 is
(select ....... from table1);
begin
open c1;
loop
fetch c1 BULK COLLECT INTO tab_t1... limit 1000;
FORALL i in 1..tab_t1.count
insert into table2 values tab_t1(i);
commit;
exit when c1%notfound;
end loop;
msg := 'Count of records inserted ' || to_char(sql%rowcount);
test_util.write_to_log (handle, msg);
close c1;
commit;
end;
My question is where should the sql%rowcount be when we use collections (after closing the cursor or before end loop or ..), to capture count of all the records that have been inserted so far. Thank you,
Lakshmi

Ramana:
There is one major difference betqween your version and Adrian's accumulating SQL%ROWCOUNT for each of the INSERTS. Adrian uses a count of 0 in the collection to exit, and you are using cursr%NOTFOUND.
I created two procedures, one p based on your logic, and a second p1 based on Adrians. I also set the limit to something less than the number of records in the table, and not an even multiple of the number of records. so, the procedures are:
CREATE or replace PROCEDURE p AS
   TYPE array_tp IS TABLE OF t%ROWTYPE;
   l_array array_tp;
   CURSOR c IS
      SELECT * FROM t;
   l_cnt1 NUMBER := 0;
   l_cnt2 NUMBER := 0;
   l_cnt3 NUMBER := 0;
BEGIN
   OPEN c;
   LOOP
      FETCH c BULK COLLECT INTO l_array LIMIT 9;
      l_cnt1 := c%ROWCOUNT;
      FORALL i IN 1 .. l_array.COUNT
         INSERT INTO t1 VALUES l_array(i);
      EXIT WHEN c%NOTFOUND;
      l_cnt2 := l_cnt2 + SQL%rowcount;
   END LOOP;
   l_cnt3 := c%ROWCOUNT;
   CLOSE c;
   DBMS_OUTPUT.Put_Line('Cursor rowcount after fetch gives: '||l_cnt1);
   DBMS_OUTPUT.Put_Line('Accumulate sql rowcount after insert gives: '||l_cnt2);
   DBMS_OUTPUT.Put_Line('Cursor rowcount before close gives: '||l_cnt3);
END;
CREATE or replace PROCEDURE p1 AS
   TYPE array_tp IS TABLE OF t%ROWTYPE;
   l_array array_tp;
   CURSOR c IS
      SELECT * FROM t;
   l_cnt1 NUMBER :=0;
   l_cnt2 NUMBER :=0;
   l_cnt3 NUMBER :=0;
BEGIN
   OPEN c;
   LOOP
      FETCH c BULK COLLECT INTO l_array LIMIT 9;
      EXIT WHEN l_array.COUNT = 0;
      l_cnt1 := c%ROWCOUNT;
      FORALL i IN 1 .. l_array.COUNT
         INSERT INTO t1 VALUES l_array(i);
      l_cnt2 := l_cnt2 + SQL%rowcount;
   END LOOP;
   l_cnt3 := c%ROWCOUNT;
   CLOSE c;
   DBMS_OUTPUT.Put_Line('Cursor rowcount after fetch gives: '||l_cnt1);
   DBMS_OUTPUT.Put_Line('Accumulate sql rowcount after insert gives: '||l_cnt2);
   DBMS_OUTPUT.Put_Line('Cursor rowcount before close gives: '||l_cnt3);
END;Note that the line l_cnt3 := c%ROWCOUNT after the LOOP but before closing the cursor would be my preference as a way to get the count if you really needed it. Now running both I get:
SQL> SELECT COUNT(*) FROM t;
COUNT(*)
        40
SQL> SELECT COUNT(*) FROM t1;
COUNT(*)
         0
SQL> exec p
Cursor rowcount after fetch gives: 40
Accumulate sql rowcount after insert gives: 36
Cursor rowcount before close gives: 40
PL/SQL procedure successfully completed.
SQL> SELECT COUNT(*) FROM t1;
COUNT(*)
        40
SQL> ROLLBACK;
SQL> exec p1;
Cursor rowcount after fetch gives: 40
Accumulate sql rowcount after insert gives: 40
Cursor rowcount before close gives: 40
PL/SQL procedure successfully completed.
SQL> SELECT COUNT(*) FROM t1;
COUNT(*)
        40You version using SQL%ROWCOUNT misses the last partial set of rows because c%NOTFOUND is TRUE after fetching the last 4 rows from the table, so you exit the loop prior to accumulating. Moving the EXIT WHEN after assigning SQL%ROWCOUNT would give the correct results.

Collection method COUNT and performance

Hi,
I use associative arrays in my application, this kind:
TYPE ADRESSETT IS TABLE OF mig.ADRESSE%ROWTYPE INDEX BY BINARY_INTEGER;
A good many times I need the count of elements in this arrays.
Of course I can use the COUNT method for this purpose.
However could it be faster to maintain a simple counter which is incremented and decremented on inserting/deleting elements
from the array?
How expensive is the COUNT method? Does the method really calculate the count every time new?

ThomasIf you know anthing about arrays/collections/linked lists etc. (all the sort of stuff taught in the basics of programming in the first year of university), then you'll know that retrieving the count of the number of 'elements' in those things is part of what they are about. The count method doesn't have to 'calculate' the count every time, as it will be held in the collections internal structure and internally maintained every time something is added/deleted. It's not going to be an expensive operation to perform as it's just going to return the value of an internal value that is already known.
Of course, it's far easier to avoid collections altogether as they use expensive PGA memory, and instead process your data using SQL directly against the database tables.

Collection classes, count

I am attempting to count occurances of a string being added in a collection class. This is what I have
class CountOccurrencesListener implements ActionListener
public void actionPerformed(ActionEvent event)
String target = targetText.getText( );
feedback.append(target + " occurs ");
int answer = countOccurrences(answer);
feedback.append(answer + " times.\n");
public int countOccurrences(String target, int answer)
int index;
answer = 0;
for (index = 0; index < manyItems; index++)
if (target == data[index])
answer++;
return answer;
It should count how many times a string was added from the text field, TargetText, but I get this error message:
"BagApplet.java": Error #: 300 : method countOccurrences(int) not found
any ideas on what I am doing wrong

To cure that error, change "int answer = countOccurrences(answer)" to:
int answer = countOccurrences(target,answer);
You either left out some code in your post or you will find additional errors.

Can I get my music collection (play counts and playlists inc.) from my iPad to my PC?

I had a problem with iTunes where I couldn't add songs to the library because I didn't have sufficient permissions to edit my iTunes library (even though I did). After a few days of tweaking administrator permissions and the like, I got really annoyed and tried re-installing iTunes to see if it would make it go away. Whilst the iTunes64Setup.exe file was downloading, I was fiddling with the .itl and .xml files in my iTunes folder and when I re-installed iTunes I had lost all my play counts and playlists. When iTunes opened, I assumed it must have overwritten the two files because when I looked at them in Windows Explorer they were both a lot smaller in size.
Obviously, I didn't sync my iPad or iPhone after this had happened, so I still have the playlists and play counts stored on them. Is there any way I can:
a) Recover a previous version of the .xml and .itl files on my laptop and use them to restore my plays?
or
b) Use iTunes Match to restore them onto my laptop?
I'm not sure about b). When you subscribe to Match, does it analyze your current library and then save it to the Cloud so you can redownload it?
I'm going to buy the new iPhone when it is released in the next couple of months so I'm willing to jailbreak my iPhone 4 if need be.
Thanks for any help.

Empty/corrupt library after upgrade/crash
Hopefully it's not been too long since you last upgraded iTunes, in fact if you get an empty/incomplete library immediately after upgrading then with the following steps you shouldn't lose a thing or need to do any further housekeeping. In the Previous iTunes Libraries folder should be a number of dated iTunes Library files. Take the most recent of these and copy it into the iTunes folder. Rename iTunes Library.itl as iTunes Library (Corrupt).itl and then rename the restored file as iTunes Library.itl. Start iTunes. Should all be good, bar any recent additions to or deletions from your library.
See iTunes Folder Watch for a tool to catch up with any changes since the backup file was created.
When you get it all working make a backup!
Or see Recover your iTunes library from your iPod or iOS device.

Collect file count and add to CSV file.

I have this script efficiently crafted by Jacques Rioux and I now what to do a little more with it.
What it currently does is look on my desktop at a select number of Folders on my desktop. It then looks at the keyword information and then returns the results to a csv file.
it looks for all the photographs; shot by Matthew. edited by Matthew etc.... with the date appended to the start and then the next time the script is run it adds the next data to the bottom of the last.
The result looks like this
19/12/2012,255,412,37,68
27/12/2012,197,342,16,26
From the fist line you can see on the 19th December 2012 I shot 255 images
No what I would like it to do is:-
a) Specifaically look in the folders of the desktop whose name begins with BH, BU, DA, DI, DO, FR, IN, NO, MA, TM, WA, PR, SE (These folders may or may not exist at the time, but are the only folders it should look at)
b) also do a file count of the contents of the above individual folders and append it to the csv file. Again a folder may not exist. Where it doesn't exist the file count must = 0 so that it can then be added to the CSV file.
This is how I hope the line to look like from the CSV file,
19/12/2012,255,412,37,68, 5,3,20,25,60,101,25,0,85,5,40,0,0
from the line above you can see that the folders NO, PR, and SE were all non existant and therefore a 0 was written in its place on the CSV file.
Below is the working script that looks for the keywords.
set spotlightqueryList to {"Shot by Matthew", "Editted by Matthew", "Shot by Shah", "Editted by Shah"}

          try
                    return quoted form of POSIX path of (f as alias) -- exists
          end try

OK i've done my homework and I have been able to get a lot closer I just need to make the search specific to a number of folders on the desktop?
Line 7 explains how I would like it to search.
set spotlightqueryList to {"Shot_by_Matthew", "Editted_by_Matthew", "Shot_by_Shah", "Editted_by_Shah"}

set thefolders to {"Desktop"}

Collect stmt

hi
collect means it adds all the numeric numeric fields based on non-numeric fields but i wnat add the single numeric field how to solve this one plz help me

Hai Kiran
go through the following Documentation
COLLECT [wa INTO] itab.
Addition
... SORTED BY f
Effect
COLLECT is used to create unique or compressed datsets. The key fields are the default key fields of the internal table itab .
If you use only COLLECT to fill an internal table, COLLECT makes sure that the internal table does not contain two entries with the same default key fields.
If, besides its default key fields, the internal table contains number fields (see also ABAP/4 number types ), the contents of these number fields are added together if the internal table already contains an entry with the same key fields.
If the default key of an internal table processed with COLLECT is blank, all the values are added up in the first table line.
If you specify wa INTO , the entry to be processed is taken from the explicitly specified work area wa . If not, it comes from the header line of the internal table itab .
After COLLECT , the system field SY-TABIX contains the index of the - existing or new - table entry with default key fields which match those of the entry to be processed.
Notes
COLLECT can create unique or compressed datasets and should be used precisely for this purpose. If uniqueness or compression are unimportant, or two values with identical default key field values could not possibly occur in your particular task, you should use APPEND instead. However, for a unique or compressed dataset which is also efficient, COLLECT is the statement to use.
If you process a table with COLLECT , you should also use COLLECT to fill it. Only by doing this can you guarantee that
the internal table will actually be unique or compressed, as described above and
COLLECT will run very efficiently.
If you use COLLECT with an explicitly specified work area, it must be compatible with the line type of the internal table.
Example
Compressed sales figures for each company
DATA: BEGIN OF COMPANIES OCCURS 10,
        NAME(20),
        SALES TYPE I,
      END   OF COMPANIES.
COMPANIES-NAME = 'Duck'. COMPANIES-SALES = 10.
COLLECT COMPANIES.
COMPANIES-NAME = 'Tiger'. COMPANIES-SALES = 20.
COLLECT COMPANIES.
COMPANIES-NAME = 'Duck'. COMPANIES-SALES = 30.
COLLECT COMPANIES.
The table COMPANIES now has the following appearance:
NAME SALES
Duck 40
Tiger 20
Addition
... SORTED BY f
Effect
COLLECT ... SORTED BY f is obsolete and should no longer be used. Use APPEND ... SORTED BY f which has the same meaning.
Note
Performance
The cost of a COLLECT in terms of performance increases with the width of the default key needed in the search for table entries and the number of numeric fields with values which have to be added up, if an entry is found in the internal table to match the default key fields.
If no such entry is found, the cost is reduced to that required to append a new entry to the end of the table.
A COLLECT statement used on a table which is 100 bytes wide and has a key which is 60 bytes wide and seven numeric fields is about approx. 50 msn (standardized microseconds).
Note
Runtime errors
COLLECT_OVERFLOW : Overflow in integer field when calculating totals.
COLLECT_OVERFLOW_TYPE_P : Overflow in type P field when calculating totals.

Regarding COLLECT stmt usage in an ABAP Program.

Hi All,
Could anyone please explain if the COLLECT statement really hampers the performance of the program, to a large extent.
If it is so, please explain how the performance can be improved with out using the same.
Thanks & Regards,
Goutham.

COLLECT allows you to create unique or summarized datasets. The system first tries to find a table entry corresponding to the table key. (See also Defining Keys for Internal Tables). The key values are taken either from the header line of the internal table itab, or from the explicitly-specified work area wa. The line type of itab must be flat - that is, it cannot itself contain any internal tables. All the components that do not belong to the key must be numeric types ( ABAP Numeric Types).
Notes
COLLECT allows you to create a unique or summarized dataset, and you should only use it when this is necessary. If neither of these characteristics are required, or where the nature of the table in the application means that it is impossible for duplicate entries to occur, you should use INSERT [wa INTO] TABLE itab instead of COLLECT. If you do need the table to be unique or summarized, COLLECT is the most efficient way to achieve it.
If you use COLLECT with a work area, the work area must be compatible with the line type of the internal table.
If you edit a standard table using COLLECT, you should only use the COLLECT or MODIFY ... TRANSPORTING f1 f2 ... statements (where none of f1, f2, ... may be in the key). Only then can you be sure that:
-The internal table actually is unique or summarized
-COLLECT runs efficiently. The check whether the dataset
already contains an entry with the same key has a constant
search time (hash procedure).
If you use any other table modification statements, the check for entries in the dataset with the same key can only run using a linear search (and will accordingly take longer). You can use the function module ABL_TABLE_HASH_STATE to test whether the COLLECT has a constant or linear search time for a given standard table.
Example
Summarized sales figures by company:
TYPES: BEGIN OF COMPANY,
        NAME(20) TYPE C,
        SALES    TYPE I,
      END OF COMPANY.
DATA: COMP    TYPE COMPANY,
      COMPTAB TYPE HASHED TABLE OF COMPANY
                                WITH UNIQUE KEY NAME.
COMP-NAME = 'Duck'. COMP-SALES = 10. COLLECT COMP INTO COMPTAB.
COMP-NAME = 'Tiger'. COMP-SALES = 20. COLLECT COMP INTO COMPTAB.
COMP-NAME = 'Duck'. COMP-SALES = 30. COLLECT COMP INTO COMPTAB.
Table COMPTAB now has the following contents:
          NAME    | SALES
          Duck    |   40
          Tiger   |   20

Collection inaccessible from Before Header process

Hi,
I have a form based on the Matrix Order application. There's a collection-based report with a bunch of text fields that can be updated and a column with a "Remove" item that basically calls a conditional Before Header process to remove the item from the collection. What I want to do is update the collection (with the values that the end-user may have entered in the updateable columns) prior to removing any item. So when the user clicks on "remove", first I do an update_member_attribute and finally I remove the item the user chose. My problem is that the updates are skipped altogether; the code is not even executed, but the removal is. It's like the collection doesn't exist at one point, but exists the next. I added an insert into a dummy table to see how many items the collection had, and it returned zero. However, the delete worked just fine. Can you have a look at my code, to see if I'm missing something obvious? Thanks a lot!
Here's the code in the Before Header:
--Here we find out how many rows in the collection
select count(*) into c from apex_collections where collection_name = 'ORDER';
insert into table1 (column1) values ('to update '||i); --This inserts "to update 0" into my dummy table.
--Update collection - nice try!
FOR x IN 1..APEX_APPLICATION.g_f01.COUNT --This code is skipped; according to the previous select, the collection has 0 rows
LOOP
c := x;
apex_collection.update_member_attribute
( p_collection_name => 'ORDER',
p_seq => APEX_APPLICATION.g_f03 (x),
p_attr_number => 4,
p_attr_value => APEX_APPLICATION.g_f01 (x) );
apex_collection.update_member_attribute
( p_collection_name => 'ORDER',
p_seq => APEX_APPLICATION.g_f03 (x),
p_attr_number => 6,
p_attr_value => APEX_APPLICATION.g_f02 (x) );
END LOOP;
--This works fine, however!!!
apex_collection.delete_member(p_collection_name => 'ORDER', p_seq => :P612_SEQ_ID);
I've tried placing the code in a "On submit" process but it's never executed. I guess that the links on report columns are not considered submits, just redirects or something else.

Using FOR .. LOOP counter in handling of PL/SQL procedures with nest. table

Hi all!
I'm learning PL/SQL on Steve Bobrovsky's book (specified below sample is from it) and I've a question.
In the procedure of specified below program used an integer variable currentElement to get reference to the row of nested table of %ROWTYPE datatype.
Meanwhile, the program itself uses a common FOR .. LOOP counter i.
DECLARE
TYPE partsTable IS TABLE OF parts%ROWTYPE;
tempParts partsTable := partsTable();
CURSOR selectedParts IS
SELECT * FROM parts ORDER BY id;
currentPart selectedParts%ROWTYPE;
currentElement INTEGER;
PROCEDURE printParts(p_title IN VARCHAR2, p_collection IN partsTable) IS
BEGIN
   DBMS_OUTPUT.PUT_LINE(' ');
   DBMS_OUTPUT.PUT_LINE(p_title || ' elements: ' || p_collection.COUNT);
   currentElement := p_collection.FIRST;
   FOR i IN 1 .. p_collection.COUNT
   LOOP
    DBMS_OUTPUT.PUT('Element #' || currentElement || ' is ');
     IF tempParts(currentElement).id IS NULL THEN DBMS_OUTPUT.PUT_LINE('an empty element.');
     ELSE DBMS_OUTPUT.PUT_LINE('ID: ' || tempParts(currentElement).id || ' DESCRIPTION: ' || tempParts(currentElement).description);
     END IF;
    currentElement := p_collection.NEXT(currentElement);
   END LOOP;
END printParts;
BEGIN
FOR currentPart IN selectedParts
LOOP
tempParts.EXTEND(2);
tempParts(tempParts.LAST) := currentPart;
END LOOP;
printParts('Densely populated', tempParts);
FOR i IN 1 .. tempParts.COUNT
LOOP
IF tempParts(i).id is NULL THEN tempParts.DELETE(i);
END IF;
END LOOP;
FOR i IN 1 .. 50
LOOP
DBMS_OUTPUT.PUT('-');
END LOOP;
printParts('Sparsely populated', tempParts);
END;
/When I've substituted an INTEGER global variable with such FOR .. LOOP counter, an APEX have returned an error "ORA-01403: no data found".
DECLARE
TYPE partsTable IS TABLE OF parts%ROWTYPE;
tempParts partsTable := partsTable();
CURSOR selectedParts IS
SELECT * FROM parts ORDER BY id;
currentPart selectedParts%ROWTYPE;
PROCEDURE printParts(p_title IN VARCHAR2, p_collection IN partsTable) IS
BEGIN
   DBMS_OUTPUT.PUT_LINE(' ');
   DBMS_OUTPUT.PUT_LINE(p_title || ' elements: ' || p_collection.COUNT);
   FOR i IN 1 .. p_collection.COUNT
   LOOP
    DBMS_OUTPUT.PUT('Element is ');
     IF tempParts(i).id IS NULL THEN DBMS_OUTPUT.PUT_LINE('an empty element.');
     ELSE DBMS_OUTPUT.PUT_LINE('ID: ' || tempParts(i).id || ' DESCRIPTION: ' || tempParts(i).description);

END LOOP;

What's wrong in code(or what I have not understood)? Help please!First code. You have collection of 10 elements:
1 - null
2 - populated
3 - null
4 - populated
5 - null
6 - populated
7 - null
8 - populated
9 - null
10 - populated
Then you delete null elements and have 5 element collection
2 - populated
4 - populated
6 - populated
8 - populated
10 - populated
Now you execute:
printParts('Sparsely populated', tempParts);Inside procedure you execute:
currentElement := p_collection.FIRST;
This assingns currentElement value 2. Then procedure loops 5 times (collection element count is 5). Element 2 exists. Inside loop procedure executes:
currentElement := p_collection.NEXT(currentElement);
which assigns currentElement values 4,6,8,10 - all existing elements.
Now second code. Everything is OK until you delete null elements. Again we have:
2 - populated
4 - populated
6 - populated
8 - populated
10 - populated
Again you execute:
printParts('Sparsely populated', tempParts);Now procedure loops 5 times (i values are 1,2,3,4,5):
FOR i IN 1 .. p_collection.COUNT
Very first iteration assingns i value 1. And since collection has no element with substript 1 procedure raises no data found.

Counting TTL pulses at high speed

Hi all,
I am using PCI-6221 board with DAQmx to count the number of TTL pulses (which varies in its frequency between 0Hz to 10MHz) at a high speed (200,000 samples/sec.) and I am having a problem when the TTL pulse frequency drops below a certain level.
I am using CTR0 to generate continuous pulse train at 200kHz frequency to feed to CTR1 Gate input. I verified that the pulse train is being generated fine.
I am using CRT1 with buffered counting to collect the count for 200,000 samples at a time (duration of 1 sec.). I got the example code (Cnt-Buf-Cont-ExtClk) and pretty much used it as is.
CTR1 Gate is coming from CTR0 Out, which is 200kHz pulse train with 50% duty cycle, and CTR1 Source is the TTL signal that I am trying to count. At first, I thought that everything was working fine with the Source signal being at around 5MHz. Then, when I had the Source signal down below about 300kHz, I noticed that the program is taking longer than 1 sec. to collect the same 200k samples. Then, when I got the Source signal down to 0Hz, the program timed out.
I am guessing that somehow the counter is not reading for the next sample when there has been no change to the count, but I cannot figure out why and how.
Any information on this and a way to get around would be greatly appreciated.
Kwang

One thing you can try is to set the counter input CI.DupCounterPrevention property, this setting will filter the input, it is possible that when the ctr 0 is slow then many of the values you are counting become zero as well and are filtered out, since they are nolonger points, the counter will not collect enough points before the time-out occurs and the counter input read times out. I am not sure if this is your issue but I found out the hard way that this occurs when I switched to daqMX where this feature was added. Let me know if it worked,

Collect information from an exprenal SQL DB and collect it into a SCOM Databag so we can collect the data, report and report on it.

The DB is collecting counts. We want to collect the counts into a bag, then once in the bag be able to report the counts (need to collect on an hourly basis)

Hi TLC426,
you can use a timed powershell or vb script to connect to the db and run a sql command against it. The result must then be parsed and returned in the property bag.
As a starting point you should have a look at Pete Zerger's blog post
http://www.systemcentercentral.com/scom-query-sql-database-for-value-in-monitoring-script/ .
Just wrap around the creation of a property bag and replace the eventlog entry generation with returning the value.
Please keep in mind that you should always should return a property bag, even it is empty.

Smart collections not reading correct number of images inside

I have an issue with smart collections for the first time. I have just set up a new workflow with 4 stages and the number counter next to the collection is counting wrong despite the images being represented in the collection. For example if I click on the smart colection I can see 10 images inside but the counter reads 3. Does anybody have this experience?
I have optimised my cataloge, however I do have some 20,000 images inside... will this reduce the ability of LR to keep up to running speed with such smart collection operations, giving incorrect readings.
What are best practices for image numbers and the arguement for running multiple cats. I've just tried in a fresh catalogue and the results were perfect. Is this an inherent limitation of Lightroom? I was under the impression that I could manage my whole archive and current projects under one roof, as it were.
Thanks,
Graeme

I suppose it would be worth optimising the catalog, if you haven't already done so.
Another idea, may be to make a fresh catalog and "import from another catalog" your current one, into that. This transfers pictures and keywords, collections, smart collections etc. But if there is something "structural" or "infrastructural" wrong with your live catalog, I'd expect that to get left behind by this process - since everyting should AFAIK get re-indexed after being brought in.
Then you'd go forward with the new catalog, if successful. Doing this makes no change to your present catalog so can do no harm to try - the various pictures' source files are simply shared across both catalogs - single file referenced by both, IOW.
One thing in your post (which I did not fully understand) suggested to me that your workflow relies at some point, on external metadata being written. If your workflow and smart collections criteria rely on the LR tracking of the status of external metadata, such as "is up to date", I believe this specific aspect has been found quite buggy and unreliable by many people: the metadata status badges etc, being sometimes rather approximate in their correspondence to reality . So if some other criterion could be found on which to base your workflow, that would probably go more smoothly .
However, if you do have more than one catalog pointing to just one set of photo source files, that aspect of writing metadata out, will of course be a little problematic - since the latest catalog to have written to the file will "overwrite", and the other catalog(s) will regard that same image as having been externally modified meanwhile.
