Variables
Let's discuss variables a bit.

Always turn on Option Explicit. You can have it automatically by going to Tools -&gt; Options in the VBE and checking the Require Variable Declaration option. This way if you have any variables not defined, the compiler will let you know.

When you don't define your variable, VBA will declare it as a Variant type that can hold any type of data. While this may be more flexible, it adds processing time to your macro as VBA decides or tests for the type. Additionally, since a Variant can be any type of data, you may miss out on valuable troubleshooting information on Type Mismatch

Variable names - give your variables meaningful names.

Personal preference - I avoid variables like i and j because they aren't descriptive. But, there's technically nothing wrong with using them as it's standard practice to iterate with i.

Standard VBA naming conventions have camelCase for local variables and PascalCase for other variables and names.


That being said -
You don't declare x or i. But those aren't vary descriptive are they? Try:
Dim slicerButtonNumber As Long
Dim tableNumber As Long

You don't have great names for the variables you do declare -
wb - targetWorkbook
sc - targetSlicerCache
si - targetSlicerItem

Extending the names using descriptive words costs you nothing and saves you headaches!
Also, here:
Set targetSlicerCache = targetBook.SlicerCaches(&quot;tbl_&quot; &amp; tableNumber)

You're using a constant - &quot;tbl_&quot;, so
Const TABLE_PREFIX as String = &quot;tbl_&quot;
Set targetSlicerCache = targetBook.SlicerCaches(TABLE_PREFIX &amp; tableNumber)

It may not seem like much, but by declaring that at top, if it ever changes, you only need to change it in one place.
Same goes for PDFCreate:
Const SHEET_NAME As String = &quot;Detail&quot;
Const POPULATION_SHEET_NAME As String = &quot;Population Detail&quot;
Const SEPARATOR As String = &quot; - &quot;
Dim detailSheet As Worksheet
Set detailSheet = ThisWorkbook.Sheets(SHEET_NAME)
Dim populationSheet As Worksheet
Set populationSheet = ThisWorkbook.Sheets(POPULATION_SHEET_NAME)
Dim file_Name As String
Dim file_Path As String
Dim aPathValue As String

file_Path = &quot;S:\MyFilefilePath\&quot;
aPathValue = detailSheet.Range(&quot;T1&quot;).Value &amp; SEPARATOR
file_Path = file_Path &amp; aPathValue
file_Name = filePath &amp; [TEXT(populationsheet.range(&quot;B1&quot;),&quot;mmm, yyyy&quot;)] &amp; &quot;.pdf&quot;

detailSheet.ExportAsFixedFormat Type:=xlTypePDF, _
    filename:=file_Name, Quality:=xlQualityStandard, IncludeDocProperties:=True, _
    IgnorePrintAreas:=False, OpenAfterPublish:=False


You don't need to Call subs, it's obsolete. Instead just use Sub argument, argument

Speed
Your set here is redundant
        For Each targetSlicerItem In sc.VisibleSlicerItems
            Set targetSlicerItem = targetSlicerCache.SlicerItems(targetSlicerItem.Name)

The For sets the items.
This is also unnecessary:
If Not targetSlicerItem Is Nothing Then

It won't be Nothing since you're only addressing the items that exist in the cache.
You can condense down
For slicerButtonNumber = 1 To 6
    For tableNumber = 1 To 7
    Set targetSlicerCache = targetBook.SlicerCaches(TABLE_PREFIX &amp; tableNumber)
        targetSlicerCache.ClearAllFilters
        For Each targetSlicerItem In targetSlicerCache.VisibleSlicerItems
            If targetSlicerItem.Name = slicerButtonNumber * 10 Then
                targetSlicerItem.Selected = True
            Else
                targetSlicerItem.Selected = False
        End If
        Next targetSlicerItem
    Next i


You can however, remove one of your loops, the slicerButtonNumber loop
Const BUTTON_NUMBERS As String = &quot;10,20,30,40,50,60&quot;
Const DELIMITER As String = &quot;,&quot;
Dim slicerButtonNumbers As Variant
slicerButtonNumbers = Split(BUTTON_NUMBERS, DELIMITER)
    

 For tableNumber = 1 To 7
    Set targetSlicerCache = targetBook.SlicerCaches(TABLE_PREFIX &amp; tableNumber)
        targetSlicerCache.ClearAllFilters
        For Each targetSlicerItem In targetSlicerCache.VisibleSlicerItems
            If UBound(Filter(slicerButtonNumbers, targetSlicerItem.Name)) &gt; -1 Then
               targetSlicerItem.Selected = True
            Else
                targetSlicerItem.Selected = False
            End If
        Next targetSlicerItem
    Next tableNumber
